My biggest mistake which a made loss on my investments and also missed out some huge profit because i was spooked and listened to some Hotcopper posters. Not knowing their background or experience i just hit the sell button after they start splashing negativity.
Despite putting in the hours, days of research and was very sure that the stock will do well and had every confident that the stock will climb in the few weeks. Yet i sold a few days later due to some negative HC posters and 1 week later the stock went up 100%. The stock im talking about is SPT. What i've learned is always trust in your own research, dont let the downrampers affect you emotionally and no one should ever tell you when to sell or stock.
Every of Legman's recent posts have a negative tone and very pessimistic.
Is he a long term investor of LCK and was he with LCK at the dawn of its time? Most importantly, is he the prophecy of LCK or a time traveller?
Can someone enlighten me as to why does people keep asking Legman for his opinions on LCK's future.

Stick to your own risk tolerance, no risk no rewards. Otherwise have faith in your investment and the company you've put the hours of researching and hard-working money into it.
